We have seen hundreds of tech acquisitions over the past 15 years, both big and small. The new generation of tech companies has seen the previous generation of tech giants stagnate or wither. They came up with an innovative idea, they grew, established themselves, then slowed down and died. But the new generation of tech companies is trying to stay young and relevant by acquiring the hot and promising start-ups. As a result, Apple Inc. (NASDAQ:AAPL), Google Inc (NASDAQ:GOOG), Microsoft Corporation (NASDAQ:MSFT), salesforce.com, inc. (NYSE:CRM), Twitter Inc (NYSE:TWTR), Yahoo! Inc. (NASDAQ:YHOO) and others have been aggressively acquiring other companies.
